Well, it sound like window manager, but this is the *only* window that
produces such behavior.

Replotting works for me as well, but python dies if the plot window
comes back to foreground again (no need to replot anything). Actually I
do not know what process is dying, but the python interpreter is heavily
affected.

Strange.
This is obviously not an R bug. I can do all this with plain R and
everything is fine. I tested i386 sarge, i386 and amd64 etch.
But doing it from python with rpy segfaults on both testing machines,
but *not* on sarge.

Well, I have no clue what I should tweak. I'm using the package defaults
on all machines and they work well for all other windows.
BTW: I tried to run it remotely from the sarge machine (connected to amd64
etch via ssh) therefore using a different xserver and the *same* window manager
that proved to work when running rpy locally. The bug is still present, but the
error message is slightly different:
*** caught segfault ***
address 0x16e8790, cause 'invalid permissions'
Creating PDFs with R via RPy works well, with no problems at all.
I don't think that this is a window manager issue, but OTOH I have no
idea what else it could be.
Best,
Michael
